Heart Rate Training Tips
Calculation Method
Uses your heart rate reserve for personalized zones
Target HR = ((Max HR - Resting HR) × %) + Resting HR
Quick estimate using maximum heart rate
Target HR = Max HR × % Intensity
We use the Tanaka formula (208 - 0.7 × age) for more accurate max HR estimation.
Heart rate zones are estimates. Stop exercising if you feel dizzy, chest pain, or extreme shortness of breath. Consult a doctor before starting a new exercise program.
